    TLDR Cryopreserved mouse whisker follicles can grow hair when transplanted into nude mice.
    The study demonstrated that mouse whisker follicles could be successfully isolated, cryopreserved using DMSO, and transplanted into nude mice, resulting in extensive hair shaft growth over 8 weeks. This process preserved the pluripotency of hair follicle-associated pluripotent (HAP) stem cells, which maintained their ability to differentiate into various cell types. The findings suggested potential applications for hair follicle cryopreservation and transplantation in hair restoration therapies and regenerative medicine, including nerve and spinal cord repair.

      A user shared a hair growth stack using minoxidil sulfate, valproic acid, bimatoprost, blue copper peptide, and other ingredients, emphasizing a gel-based formula for better skin tolerance. Another user suggested adding a 5-alpha-reductase inhibitor like finasteride or dutasteride for more effective long-term results.

      community Weed/THC effects on hair growth/hair loss, and vitality of organ-culture human follicle studies (research review)

      in Research/Science  5 upvotes 1 year ago
      Cannabis and THC may have mixed effects on hair, with some studies suggesting potential negative impacts on hair growth in isolated hair follicles, but these results are hard to apply to living humans. Treatments like minoxidil and finasteride are commonly used for hair loss, and the effects of cannabis might be neutral or vary based on individual factors.
